Previous studies have stressed that inflation dynamics exhibit substantial dispersion across sectors. Using US producer price data, we present evidence sectoral persistence is negatively correlated with market concentration, which difficult to reconcile the prediction of standard model monopolistic competition. To better explain incorporate imperfect common knowledge into competition introduced...

osteogenesis imperfecta is a rare inherited connective tissue disorder with an expression that varies from mild to severe disease affecting bone, sclera and middle ear. fertility is preserved, especially in those patients with type 1. we present hereby a pregnant woman with osteogenesis imperfecta that had over 30 fractures in long bones and vertebrae. the object of this report was to determine...

the traditional economic production quantity (epq) model assumes that during the production process no imperfect item is produced. but in the real production system, due to imperfect production process or other factors, imperfect quality items may be produced. furthermore, it is well-known that the total production-inventory costs can be reduced by reworking the imperfect quality items produced...

Photonic Greenberger-Horne-Zeilinger (GHZ) states serve as the central resource for a number of important applications in quantum information science, including secret sharing, sensing, and fusion-based computing. The use photon-emitter entangling gates is promising approach to creating these that sidesteps many difficulties associated with intrinsically probabilistic methods based on linear op...

IMPERFECT competition is a pervasive part of modern industrial economies, where high levels of concentration in product markets often coexist with unionised labour markets. Most standard macroeconomic models, however, assume that markets are perfectly competitive. This paper provides a simple framework in which we are able to explore some of the implications of imperfect competition for the mac...

The present investigation is to study the surface waves propagation with imperfect boundary between an isotropic elastic layer of finite thickness and a homogenous isotropic thermodiffusive elastic half- space with rotation in the context of Green-Lindsay (G-L model) theory. The secular equation for surface waves in compact form is derived after developing the mathematical model. The phase velo...
